The bag was too heavy and she just couldn’t lift it up. The man behind her got very impatient. He, too, was waiting to check in his luggage. “What’s wrong with this girl?” He said, “Why doesn’t she hurry up?” He moved forward and placed his bag on the counter, hoping to check in first. He was in a hurry to get a good seat. Maria was very angry, but she was very polite. And in her best English she said, “Why are you so upset? There are enough seats for everyone on the plane. If you are in such a hurry, why can’t you give me a hand with my luggage?” The man was surprised to hear Maria speak English. He quickly picked up her luggage and stepped back. Everyone was looking at him with disapproval. 6、Maria’s story happened on her way back to Santo Domingo. A、T B、F 参考答案:B

大学语文B·平时作业2020春华南理工大学网络教育答案

一． 1. 子路、曾皙、冉有、公西华侍坐 翻译： 子路、曾晳、冉有、公西华陪孔子坐着。孔子说：“不要因为我比你们年长，而停止讲了。你们常常说：“不了解我。”假如有人了解你们，那么你们会怎样呢？” 子路匆忙的回答说：“一个有千辆车马的诸侯国，夹在大国中间，加上打仗，继且遇上饥荒，如果让我治理这个国家，等到三年，可以让他们变得勇猛，并知懂得礼仪道德。” 孔子听了他的话露出微笑。 “冉求，你觉得怎样？” （冉求）回答说：“方圆六七十或者五六十的国家，如果让我去治理，等到三年，可以使百姓富足起立，至于修明礼乐，就等贤人君子了。” “公西赤，你怎么样？” （公西赤）回答说：“我不敢说能做到什么，只是愿意学习。宗庙祭祀的工作，或者是诸侯会盟，朝见天子，我愿意穿着礼服，戴着礼帽，做一个小小的傧相。” “曾点，你怎么样？” （曾点）弹瑟的声音逐渐稀疏，铿的一声，放下瑟直起身来，回答说：“我和他们三人的说法不同！” 孔子说：“那又何妨呢？不过是各自说说自己的志向！” （曾点）说：“暮春时节，春天的衣服已经穿着了。（我和）五六位成年人，六七个少年，到沂河里洗澡，在舞雩台上吹风，唱着歌走回家。” 孔子长叹一声说：“我是赞成曾点的想法！” 子路、冉有、公西华都出去了，曾晳最后走。曾晳问（孔子）：“他们三个人的话怎么样？” 孔子说：“也不过是各自谈谈自己的志向罢了！” （曾晳）说：“你为什么笑仲由呢？” （孔子）说：“治理国家要讲理让，可他的话却一点不谦让，所以笑他。难道冉求所讲的就不是国家吗？怎见得纵横六七十里或五六十里的地方就不是国家呢？难道公西赤所讲的不是国家吗？宗庙祭祀和诸侯会同之事，不是诸侯的大事又是什么呢？如果公西赤只能给诸侯做一个小相，那谁能来做大相呢？” 2. 伯夷叔齐列传 翻译： 世上阅览群书多人很多，但仍然会来考实六经。《诗经》《尚书》虽残缺不全，然而有关虞、夏史事的记载还是可以看到的。唐尧将要退位的时候，决定禅让给虞舜。而虞舜以及后来的夏禹，四岳九牧都一致推荐，才试任官职管理政事几十年。待到他们的功绩已经建立，然后才把帝位传给他们。这表明，天下是最珍贵的宝器，帝王是最大的继统，传交帝位是这样的难啊！但是，有的人却说：尧要将帝位让给许由，许由不肯接受，并以此为耻而逃避隐居起来。到了夏代，又有卞随、务光两个人不肯接受帝位，双双投水而死。这些，又怎么说起呢？太史公说：我曾经登上箕山，那上面居然有许由的墓呢。孔子排列论述古代的仁人、圣人和贤能之人，象吴太伯、伯夷一类，记载十分详尽。我所说韵许由、务光，他们的德义是极高的，而有关他们的文字经书里记载得很少，这是为什么呢？ 孔子说：“伯夷、叔齐，不记旧仇，因此很少怨言。”又说，他们“追求仁而得到了仁，又为什么怨恨呢？”我悲怜伯夷的心意，读到他们留下的逸诗而感到事实是令人奇怪的。他们的传记里写道： 伯夷、叔齐，是孤竹君的两个儿子。父亲想立叔齐为君，等到父亲死后，叔齐又让位给长兄伯夷。伯夷说：“这是父亲的意愿。”于是就逃开了。叔齐也不肯继承君位而逃避了。国中的人就只好立他们的另一个兄弟。正当这个时候，伯夷、叔齐听说西伯姬昌敬养老人，便商量着说：我们何不去投奔他呢？等到他们到达的时候，西伯已经死了，他的儿子武王用车载着灵牌，尊他为文王，正向东进发，讨伐纣王。伯夷、叔齐拉住武王战马而劝阻说：

【7A版】2018年华南理工大学网络教育计算机应用基础平时作业

1.画出冯诺依曼结构模型，并简述冯.诺依曼原理的基本内容。 答：冯诺依曼体系结构有以下特点： （1）计算机处理的数据和指令一律采用二进制数的形式表示；（2）指令和数据不加区别混合存储在同一个存储器中； （3）顺序执行程序的每一条指令； （4）计算机硬件由控制器、运算器、存储器、输入设备和输出设备五大部分组成。 程序执行过程实际上是不断的取指令、分析指令、执行的过程。因为其结构特点，冯诺依曼的计算机本质上讲是采取串行顺序处理的工作机制，即使有关数据已经准备好，也必须逐条执行指令 2.简述启动控制面板的常用方法。（至少列出三种） 答：启动的方法有（以Windows7为例） （1）点开始，选择控制面板打开。 （2）打开我的电脑，选择控制面板打开。 （3）点开始-运行，输入命令control，回车打开控制面板。 3.什么是存储器？内存储器与外存储器之间有什么异同点？ 答：(1)计算机存储器是记忆部件，用来存放程序和数据，是计算机的重要组成部分。计算机中全部信息，包括输入的原始数据、计算机程序、中间运行结果和最终运行结果都保存在存储器中。它可分为：内部存储器,外部存储器。 A.内存（内部存储器）：其作用是用于暂时存放CPU中的运算数据，以及与硬盘等外部存储器交换的数据，只要计算机在运行中，CPU就会把需要的数据调到内存中进行运算，当运算完成后CPU再将结果传送出来，内存的运行也决定了计算机稳定快慢的运行。 B.外存（外部存储器）一般用于掉电存储，比如硬盘、U盘、移动硬可以存储程序代码或用户数据资料。 (2)内存和外存主要的区别： A.速度不同。内存要比外存速度至少快上百倍，外存通常较慢，运行时要先加载到内存运行。
